Headed for trouble if you get that deep.
Air Intake: snorkel
Raise all vent lines : fuel tank , water pump , ft. & rear diffs
Even exhaust will need to be raised.( if it stalls water will get in the motor quick )
Use DIELECTRIC grease on every connection on the entire machine including all grounds & ECU.
There are both successful & Unsuccessful stories of submerging these machines.
Anything above the fuel tank filler neck gets questionable if it stalls. ( at least keep water level below exhaust outlet )
Others with 1st.hand experience will chime in may be share $$$$ drain on the old bank account amount off work involved.
Standing water is one thing.
Crossing a raised creek or river is another , doesn't take much current when that deep to loose traction the bigger the tire sooner it floats ( seen it happen to Jeep's & ATV's )
In the Adirondacks seen creeks raise several feet in just 2--3 hours , put more wood on the fire wait 24 -- 48 hours water level goes down then head home.
